Hi I have a 837 ADSL Router and site to site VPN is configured with VPN Concentrator, also we are using inter net from the same line, the problem is i have ftp clinet which upload data in to my head office over VPN, when i transfer small size of data it works like 10 KB ... but when i transfer morethan 100 KB it disconnect after a while.

Your config looks quite allright although I'm always a bit reluctant in using very long ACL's, which you have done here.
I have two tips to aid in troubleshooting:
1: run a debug dialer and make an ftp transfer that causes the line to disconnect. You might get a disconnect cause or some other vital clues
2: try what happens when you deactivate the access-list. there is little risk in running without security for a short while.

Hello,
in addition to what Leo says, you might want to try and configure some sort of traffic prioritizing for your FTP traffic. It might just be that large files starve your bandwidth, and you get disconnected because of other traffic.
Try and configure the following on your router:
ip cef
!
class-map match-all FTP
match protocol ftp
!
policy-map FTP_PRIORITY
class FTP
bandwidth percent 50
!
interface Ethernet0
service-policy output FTP_PRIORITY
If your router does not support the 'match protocol ftp' command, use the following config:
class-map match-all FTP
match access-group 112
!
policy-map FTP_PRIORITY
class FTP
bandwidth percent 50
!
interface Ethernet0
service-policy output FTP_PRIORITY
!
access-list 101 permit tcp any any eq 21
Just a thought, but might be worth trying...

We have only one user browsing internet, i don't think to prioritise traffic....
thanks
